Sure looks identical to my B&M J converter. Mine measures about 10" also. I can get pictures later today of both sides and if you'd like and see what's marked on it. I know there wasn't very many markings. If you send it away to get freshened, send it to PTC and have them put a new snout on the crank side. They were very thin and cracked along the welds, been there - done that. Wade
